LED low beam lamps h4. Types and overview of models of h4 LED lamps. Which LED lamps are better?

Recently, more and more different light bulbs for installation in optics have appeared on the domestic market. These devices are produced both at domestic and foreign enterprises. LED bulbs are just beginning to gain popularity today, but many motorists already prefer H4 type bulbs.

Description of automotive LED lamps

What are Color Enhanced LEDs? How are low and high beam bulbs connected, what is the connection diagram and which LED bulbs are best to choose? For H4 xenon to work well, you need to use high-quality devices and always monitor their performance.

Design

Let's start with the design of H4 lamps for a car. This device has an aluminum radiator, a ventilation device located at the end, as well as two diodes - low beam and high beam. In its design, xenon H4 is very similar to a halogen light bulb.

In order for the H4 bi-xenon bulb to work as it should, it must be equipped with a lens. The best option in this case would be to purchase factory-made diode high and low beam headlights, which were already equipped with cooling radiators at the factory. Otherwise, the H4 light bulb will not light as expected, in particular when it comes to high beam lighting. Our car enthusiasts often note in reviews that the problem usually lies in the high beams. The pinout of the H4 lamp is fundamentally different from the halogen lamp.

Operating principle

How do H4 LED car bulbs work? In the long-range lighting mode, the optics operate on the principle of a conventional spotlight. That is, the spiral of the H4 car lamp, located at the focus of the parabolic reflector, when turned on, begins to form an enlarged light beam at the output, parallel to the road surface. The surface of the reflective component is also used for this purpose.

As for the low beam operating mode of the H4 car lamp, in this case the device uses a second spiral located directly in front of the focus of the optics. This spiral is covered from below with a small screen made in a special shape. In this case, H4 xenon filters out part of the light flux during operation, resulting in the formation of a special spot in the required shape. In this mode of operation of the light bulb, the upper part of the optics reflector is used, while the H4 flow itself is directed slightly downward. The luminous flux should ideally hit the road surface in front of the vehicle approximately 50 meters (video author: Igor Shurar).

How is H4 xenon switched? The switching principle is that the bulb of the device moves from one position to another, unlike halogen ones, where the filament coils function alternately. Xenon H4 is equipped with low beam chips, which always work, and high beam chips are connected to these chips.

Advantages

So, what are the advantages of xenon H4:

Consumes significantly less energy, which generally reduces the load on the vehicle's on-board network.
Quite a long service life, it is at least 50 thousand hours.
Compared to halogen ones, H4 xenon will be more reliable when exposed to vibrations and shocks, due to the absence of a filament.
The luminous flux of the xenon in question is quite large, ranging from 1800 to 3600 lumens.
A more pleasant color of light output is white or blue.

Which LED lamps are better?

Which lamps that can increase the luminous flux are better? Below is a rating of the most optimal lamp options for installation in optics.

Option 1

This Chinese-made option is one of the most budget-friendly. The design of such a device is based on three diodes; the power of the element ranges from 20 to 30 watts. This H4 xenon is powered by an external driver, and thanks to the aluminum housing, heat is supplied to the cooling radiator. As for the fan itself, it operates quite quietly.

As practice shows, usually there are no problems when installing such devices, but in some cases the on-board computer does not want to perceive such optics. This problem can be solved by additionally installing a so-called resistor blende.

To provide low beam lighting, two chips are used, installed across the axis itself. When the driver turns on the high beams, another chip installed at the focal point of the reflector device comes into operation. In fact, such a bulb uses exclusively the upper part of the reflector to provide distant lighting. As shown by the test of automobile lamps with increased luminous efficiency H4, this option provides diffuse low-lighting, most optimally illuminating the road only at a distance of fifteen meters.

As for the quality, it is average, one might even say unsatisfactory. These bulbs cost up to $40. If you want to achieve good road illumination, then it is better to avoid devices of this type.

Option 2

The cost of this option is around 50-55 dollars, the light bulb has a built-in driver and cooling system. When the engine is running, you can hear the hum from the fan operation, even if you are outside the car. As practice shows, sometimes the electronics from the driver can interfere with the operation of the radio. As for the design, in general this option is similar in design to the sample described above, but there are some innovations. In particular, a fourth chip is used in this case to ensure good long-range illumination. A reflective device is installed next to the diodes, above and below, which allows 100% use of the luminous flux from the lamp.

Despite the fact that the diodes themselves are located on the same line, they are not installed on the same axis, but, albeit slightly, are shifted down or up. As for the low beams, they are located not along the axis, but across. Of course, this ultimately affects the focusing of lighting from the negative side - when the low beam is on, only two chips function, when the rear light is turned on, two more chips are activated. That is, in fact, this is not long-range lighting, but near + far.

Option 3

The vertical layout of the LEDs of this sample is complemented by a special screen for low-beam lighting; the price for a set of such bulbs is about $50. It should be noted that the kit is complemented by a light filter in the form of a sleeve, as a result of which you can reduce the color temperature, that is, make it yellow. The bulbs of this sample are made on the basis of four diodes, and consuming 40 watts, they should produce about 4500 lumens declared by the manufacturer, but this, of course, is not true.

As with the options described above, when the high beam is activated, a second beam is activated, complementing the illumination of the near beam. Thanks to the presence of special screens, the light-shadow boundary is better visible - at least it is there, unlike the options described above. In practice, the right side is not illuminated as well as we would like, but the brightness of such xenon is much higher when compared with halogen lamps.

Option 4

This Chinese-made H4 xenon is fundamentally different from the samples described above. The light bulb design includes 16 small diodes located along the optical axis. The switching principle is similar to devices with a filament coil - groups of LED elements function separately and are switched on in turn to provide low and high beam lighting.

The diodes responsible for the operation of low beam lighting are covered with a screen. The cost of such a sample is about $65 if ordered directly from China. If you decide to purchase a set in a local store, add another 15-20 dollars to the price.

The cooling principle of the device is passive, this is due to low power consumption. There is no fan, which means the device cannot fail if it breaks, but as a result, more stringent conditions are applied to the cooling of the radiator. The light bulb shines well in both low and high beam conditions - in fact, the brightness level is just under 3 thousand lumens. Working in low beam mode, the diodes form a light beam with a clear upper boundary. In general, it can be argued that this option is the most optimal in terms of technological as well as constructive technologies.

Video “Testing H4 type light bulbs”

Practical testing of LED bulbs for cars is shown in the video (the author of the video is Test Lab Avtolamp tests).

H4 diode lamps are installed in headlights. The main feature of such lamps is that they are suitable for both distant and near lighting at the same time.
There is a large selection of h4 lamps on the market. You can choose almost any one, the main thing is that they have an appropriate base. And yet, among the reviews you can find both positive and negative. Let's look at how h4 diode lamps work, what is their difference, how to install and use them correctly.

LED H4 lamps can be both dimmer and brighter than their halogen and xenon counterparts. This indicator depends on the type of LEDs and lamp power. The highest quality ones include epistar, samsung and cree. They are distinguished by excellent performance, warranty and brightness.

For high-quality operation, LED lamps N4 must have a base suitable for power. If its parameters do not correspond, then installing such a lamp is useless. For h4, the following indicators are suitable: 1650 for high beam and 1000 for low beam.

Diode lamp h4 - features

These lamps combine two high-power LEDs at once. The LED for low beam is located at the top, and for high beam it is located at the bottom. The size of the LEDs is important. No matter how strange it may seem, the smaller the diodes, the better. The headlights were initially designed according to the spiral of a halogen lamp. Therefore, the diodes should be close in size to it.

H4 diode lamp – cost

There is a huge variety of such lamps on the market. Chinese industry diligently produces a large assortment. You can find h4 lamps for 1000 rubles and 5000 rubles.
Pay close attention to the characteristics! Often they are indicated incorrectly or completely incorrectly.
Necessary parameters for work:
High beam brightness – 1500 lumens,
Low beam brightness – 1000 lumens,
Power – 17 watts,
The presence of a radiator with a cooling system.
The lamp efficiency should be about 100 lumens per watt.

Diode lamp h4 – brightness

Most often, the brightness in stores is indicated at random. Most often they will tell you the total brightness for both low and high beam. For example, 3000, 3800, 4500 lumens is not the brightness of the high beam, but for both LEDs.
In fact, brightness above 2500 is unrealistic.
Make sure that what you buy is not a Chinese counterfeit. As a rule, Chinese analogues with similar names are much larger in size.

H4 LED car lamps - device

The light bulb consists of the following parts:
Two diodes (for low and high beam)
Fan (located at the end)
Aluminum radiator.

In appearance it resembles a halogen lamp, but headlights for halogen lamps are usually not designed for LEDs. The reason for this is that the spiral area in a halogen lamp is much smaller than an LED. In order for an LED lamp to work correctly, it will need a lens.

Advantages of h4 LED headlights

They are popular for a reason. There are a number of reasons for this. Let's name the main ones:
They consume little electricity. This significantly saves your money and creates much less voltage on the machine's electrical system.
They work for a long time. LEDs have a much longer lifespan than halogen or xenon LEDs. Manufacturers quote figures up to 50 thousand hours. Even if these figures are exaggerated three times, they still exceed analogues.
High resistance to external influences. LEDs are not afraid of moisture and dust. They can also easily withstand even large vibrations, shocks, etc. The reason for this is that they do not have a filament.
The luminous flux is quite large. The declared luminous flux of LED lamps is 1800 – 3600 lumens.
Nice color temperature. LEDs for h4 headlights are those that emit white light. It is as comfortable as possible for the human eye.
Environmental friendliness. These lamps do not contain any dangerous substances such as mercury. Even if the lamp is damaged, it will not harm your health.
The light from LED lamps does not dazzle. This is a very big plus, because if you blind someone coming towards you, you risk getting into an accident.
Lights up quickly. More precisely instantly. Unlike analogues, LEDs do not need time to light up - they light up immediately.

Bottom line

Having considered the main points in the operation of h4 LED lamps for cars, we can summarize the following:
They have a number of undeniable advantages (long service life, pure white light, economy, etc.)
When choosing, you need to carefully ensure that you are not sold a fake.
When connecting, you need to check that all the parameters of the car and the LEDs match so that they work as expected.

I’ve been thinking for a long time about buying LEDs for the headlights, but everything I came across before was depressing - some idiotic fans and nameless Chinese LEDs... And then in the summer of 2016 I came across THIS.

These lamps are essentially a Chinese copy, and the Chinese even corrected the Philips joints. Why these lamps? And based on a combination of factors: The lamps are well made, the driver and lamps are dismountable and, in theory, repairable. The design uses top-end Lumileds Luxeon ZES LEDs, the geometry of the LEDs and reflector is as close as possible to the standard halogen, the power driver is present and is made as a separate unit, the lamp cooling is passive, in the form of flexible copper belts of a decent area, allowing you to remove radiators in the headlight housing, and pull it out, cutting a slot in the rubber plug. These design features, including the absence of a fan, made it possible to assume that this generation of LED lamps is already capable of shining correctly, brightly and for a long time.

So, the product is delivered in a rigid cardboard box, inside of which, in polystyrene foam cells, there are lamps and drivers. So, despite all the efforts of the Russian Post visible on the box, the contents were not damaged at all.

The product was purchased with my own money.

Here it is, my precious...

LEDs are already familiar to us from, however, here they shine 2-3 times brighter. Apparently the operating current is significantly reduced so that with such a small radiator they heat up within reasonable limits. Probably the LEDs here are, after all, Luxeon ZES of the first generation.

As you can see, the geometry of the light source is as close as possible to the filaments of a halogen lamp.

The lamps are installed quite simply. If you change regular lamps without any problems, then you won’t have any problems with these either. Although, if you want to place all the components inside the headlight, it is easier to remove the entire headlight. That's exactly what I did. From the point of view of thermal conditions, this is not the best option, but there is no need to cut extra holes in the headlight, it remains completely standard and, if necessary (for maintenance, for example), the lamps are changed to standard halogen in 5 minutes. In general, I measured the temperature after 30 minutes of operation - +125C on the LEDs, 50-60C on the radiator. Manufacturer states working LED temperature up to +135C, so I found this mode satisfactory.

Instructions for lamps

I want to immediately reassure the paranoid - the lamps have been working in this form every day since September 2016. and there are no problems with them. And according to customer reviews, there are practically no failures.

The light-shadow boundary and the far-near operating modes can be seen in the video below.

Here you need to keep in mind that the left headlight is a 10-year-old original, and the right one is a crappy non-original, but new. Hence the slight difference in the brightness and geometry of the headlights.

A short video demonstrating the operation of lamps on the road.

The lamps shine beautifully. Of course, they are far from good lensed xenon, but they are also very far ahead of ordinary halogen. Compared to the Osram NightBreaker Unlimited, the lamps provide less light in the near zone at the bumper, but noticeably more in the far zone. The result is more uniform illumination, improving visibility, without a bright spot of light in front of the bumper.

Let's try to look for conditional shortcomings.

1. Snow/ice on the headlight does not melt. Previously, you turn on the neighbor and after a couple of minutes everything melted away. Now I have to clean it regularly.

2. You cannot turn on the high and low diodes at the same time, even for a couple of seconds. The car has such a function and it works fine with halogen lights, but here the driver turns on either the low beam or high beam diodes, but not both groups at once.

3. 6500K - although the diodes are not bluish, the light under artificial city lighting is not very contrasty. Well, not very good on wet asphalt. However, almost everything on it is not very good.

4. Greater unevenness of illumination compared to halogen - on the illuminated surface, if you look closely, you can see the gaps between the LEDs and the LEDs themselves, etc.

5. Formally, these lamps are not an appropriate light source for a halogen headlight and theoretically, you can be charged under the article “for collective farm xenon”. Although in practice, working LED lamps look completely normal, with STG and daws, and even if they excite traffic police inspectors, it is only when they ask questions - why does it shine so well? And where can I buy this?

6. They are a bit expensive. For this money you can buy two sets of Osram NightBreaker Laser or Unlimited and ride quietly for 3-4 years. And for an undemanding user, standard light bulbs cost 150 rubles per piece. enough for the entire life of the car. Even if diode lamps last 3-4 years, by that time they will already be obsolete, because there will be new LEDs - smaller, better, brighter, more energy efficient. So saving due to a large resource is only in theory and advertising brochures. We must clearly understand that these lamps will never pay for themselves financially. But they are worth it - I installed them instead of Osram NightBreaker Unlimited and did not regret it for a second... Why? Well, I have not yet met people who are satisfied with the headlights on H4 lamps. There is only one lamp in the headlight and either the low beam or the high beam can work at the same time. As a result, the high beam is a C grade and the low beam is so-so. In separate optics, you can turn on both the near and far beams at the same time, but here the only option to achieve suitable light is “reinforced” halogen lamps or LED lamps like these.

LED H4 lamps are used in two-headlight systems; their main purpose is the headlight of a car. The design provides diodes that perform various tasks. Thanks to this, LED light bulbs in this design are used when organizing low and high beams. You can conduct your own test of different lighting elements or use proven information about the operation of the main types of car lamps.

Design and principle of operation

In addition to a certain number of light-emitting elements, the design provides a cooling system: radiator + fan, as well as an H4 base. As a result, the LED Headlight H4 bulbs are quite massive.

The main thing when choosing a lamp is that its dimensions correspond to the dimensions of its halogen counterparts.

But the main thing is that their dimensions correspond to the dimensions of their halogen counterparts. The diodes are positioned differently than the filaments in a halogen, which provides a slightly different lighting effect.

The principle of operation of LED Headlight lamps is to obtain light energy by converting the electrical equivalent. When the high beam is turned on, all light-emitting elements provided in the design are used.

For low beam, only a portion of the LEDs are used. Accordingly, the main area of application of LED Headlight H4 is the organization of automotive lighting, in particular, low and high beam.

To install instead of halogens, it is important to select the size of the light source as accurately as possible. But today there are optical systems designed specifically for LED lamps.

Types, technical characteristics

The main differences between light sources of the LED Headlight H4 type are: the shape of the product, the type of light-emitting elements, their number and location, as well as the type of cooling system. As for the last of these parameters, there are light bulbs with active and passive heat removal.

Chinese model G9X 2015, passive radiator with flexible ribbon elements

The difference between them is the presence of a fan. The shape of the LED headlight H4 can be different: with 2-3-4 edges, which determines the way the diodes are arranged. There are flat and cylindrical products; in each case, the light-emitting elements are arranged differently, which is influenced by their number and size.

Models with active radiator cooling: this makes it possible to use powerful LEDs to illuminate the road

However, tests show that not all design options for such light sources are equally effective. The closest to real lighting, similar in light boundary to “halogens,” are lamps in which the chips are installed in the same way as the filaments in their halogen counterparts.

The CREE company produces five series of high-power LEDs, different in design and type of crystal used: XR-C, XR-E, XP-C, XP-E and MC-E.

Also, in some models, a so-called curtain is installed on one of the diodes, thanks to which, when the low beam is turned on, a light border of the desired shape is created.

The number of light-emitting elements can be different: from 2 to 18 pieces, and the type is usually represented by the following options: SMD 2323, SMD 5050, CREE (with different parameters). The power varies from 4 W to 50 W, which is determined by the type of diodes used in LED Headlight H4 bulbs and the cooling system. More powerful chips and forced ventilation increase not only the level of load created, but also the cost of such a product.

In addition to the power value, the lighting element in this design is characterized by other parameters:

power supply (12/24 V);
luminous flux: sufficient for low beam is 1,000 lm, for high beam – 1,500 lm, in addition, LED lamps headlight H4 are capable of providing much higher radiation intensity;
type of diodes, usually the manufacturer indicates the brand CREE, SMD, less often the parameters are written, for example, 1512;
color temperature – for sources of this design, the normal range is 4,000-6,000 K;
degree of protection;
temperature range during operation of the LED headlight H

Often, instead of chips from well-known brands (for example, CREE), nameless analogues are installed. You can distinguish a fake by visual signs: the second option is usually characterized by non-standard sizes: larger than the original.

Design features of H4 lamps

To understand which LED lamps will work correctly on a car with halogen headlights under the H4 base, you need to have a good understanding of exactly how such a headlight works.

Headlights for the H4 base have only one reflector, which works for both “low” and “high” beams. The H4 lamp has two light-emitting filaments built in, and one or another mode is activated by turning on the first or second filament (or both at once). Changing the focal length of the reflector ensures its operation in one mode or another.

One of the main problems that arises when installing non-standard lamps in headlights is incorrect distribution of the light beam, and as a result, blinding oncoming drivers.

As a rule, this is due to the fact that the location of the light sources in non-standard lamps does not correspond to their location in standard H4 halogen bulbs. A discrepancy of just a couple of millimeters is already a big problem for oncoming drivers.

Thus, the key point when choosing any non-standard lamps for installation in a headlight with an H4 socket will be the need to select only lamps in which the light sources are located exactly in the same places where they are located on standard H4 halogen lamps. Otherwise, the headlight will not work correctly.

What types of H4 LED lamps are there?

The key element that determines the shape and size of an LED lamp is the light source itself - the LED. LEDs come in square, rectangular and cylindrical shapes, ranging in size from fractions of a millimeter to several millimeters.

Each LED has its own luminous flux. Achieving the required amount of light produced by the lamp is ensured by increasing the number of LEDs in it (up to 20 pcs). It is the shape and size of the LEDs, as well as their number, that determines what size and dimensions the light bulb itself will be.

To ensure proper distribution of the light flux, sometimes H4 LED lamps use special curtains that block one or more diodes (similar to bi-xenon lamps). Such curtains significantly complicate the design of the lamp, and therefore its cost.

Also, the dimensions of the light bulb (and its cost) are greatly influenced by the cooling system of the lamp. For any LED to operate, a “driver” is required - a special microcircuit that heats up noticeably during operation. To prevent the driver from overheating and failing, the heat must be removed. The cooling system can be passive or active.

Some LEDs require a small chip that doesn't get very hot, and a passive cooling system is sufficient for it to work properly. The passive cooling system consists of a large number of fins (either fixed or soft and loosely attached, looking like a “bundle” at the base of a light bulb, also called a flexible radiator).

For other LEDs that require a powerful and very hot “driver”, a passive cooling system is not enough. For normal operation of a lamp with such diodes, a special fan (cooler) is built into its design - approximately the same as in computers. The presence of a cooler in a lamp significantly complicates its design, increases its size and cost.

How to choose LED lamps

To understand which H4 LED lamps are suitable for a particular car and which are not, you need to highlight several criteria that you should pay attention to first.

The first thing you need to figure out is the location of the LEDs in the lamp. In some LED bulbs, they may not be located in the same places where the filaments of a standard H4 lamp are located, which will lead to incorrect distribution of the luminous flux in the headlight (the headlights will blind oncoming traffic).

The easiest way to find out the location of the LEDs is to ask to look at the light bulb in a store, place a standard H4 light bulb on top of the LED light bulb you are planning to buy, and look “heads up”. If the location of the diodes and filaments does not coincide, it is better to refuse such a light bulb.

The second thing you need to find out is the size of the light bulb itself. A considerable number of LED lamps are much larger in size than standard H4 halogen lamps. Not every car's headlight can accommodate a large bulb. There are often cases when car owners, in order to install LED bulbs, cut holes in the rear headlight cover and then seal them. Not an easy job, it is highly advisable to avoid it. It is also possible to install special enlarged rear covers on the headlights, although finding them on sale is not so easy.

The third thing to remember is the color and amount of luminous flux of the LED bulb. In theory, to improve illumination, the luminous flux from the lamp should be as strong as possible. But in practice, even with correctly adjusted headlights, too much luminous flux can create problems for oncoming cars. If there is too much light, it begins to “scatter” in all directions.

According to the standards, the luminous flux of a standard H4 halogen lamp is no more than 1000 Lumens for low beam and no more than 1500 Lumens for high beam. When choosing an LED lamp, you should not choose models with a luminous flux more than 1.5 times higher than the “standard” one. That is, 1500 Lumens for low beam and 2250 Lumens for high beam will be quite enough.

As for the color of the light flux, it is worth saying that the best conditions for the human eye to perceive the surrounding environment are created by sunlight. That is, on a good sunny day a person is able to see all the smallest details. At the same time, any other lighting - bright white, or even bluish-violet - no longer guarantees that a person will see just as well.

That is, the best color for lighting is daylight white (sometimes with a yellowish tint). You can often find LED lamps on sale that shine with “warm” light - this is the very color of lighting that is most suitable for perception by the human eye. When choosing lamps for headlights, it is best to look for this color (or just white).

For automobile lamps, the color of the luminous flux is usually indicated by temperature in degrees Kelvin. The most optimal color temperature is usually 4000K-6000K. At 4000K the color of the light flux is the warmest; at 6000K the color of the light flux approaches daylight white. It is in this range that the human eye perceives surrounding objects as clearly as possible, and it is this color temperature that is best chosen when purchasing LED lamps.

Top 3 Best H4 LED Bulbs

All H4 LED lamps that can be found on sale are divided into three categories - branded (and very expensive), slightly less expensive and made on the basis of high-quality branded LEDs, as well as cheap consumer goods.

Today, some of the best offers on sale can be considered lamps under the well-known European brand Philips, as well as the American brand CREE. However, it is necessary to make a reservation that the cost of these lamps may surprise an unprepared buyer - it starts from 9 thousand rubles.

You can also find many alternative options on sale - products under unknown Chinese brands, but produced on the basis of Philips or CREE LEDs. It is also worth mentioning the Korean developers of LEDs; their products have recently been in no way inferior to European and American ones. Such lamps not only have an acceptable cost, but can even boast of high quality (though not all, but only part).

As for cheap consumer goods, installing such lamps in headlights not only guarantees the dissatisfaction of oncoming drivers, but can even cause the headlight to fail.

Among car owners, the most popular H4 LED lamps are:

X-LITE LED H4 G7

Very interesting LED lamps from a Chinese manufacturer using high-quality European Philips Luxeon LEDs.

The lamp is one of the few Chinese products where increased attention is paid to the placement of LEDs. The location of the LEDs responsible for the “low” and “high” beam most accurately repeats the location of similar filaments in a halogen light bulb, which ensures the correct focal length and distribution of the luminous flux. Thanks to Philips Luxeon LEDs, the light output of the lamp

The Chinese are accustomed to indicating the total luminous flux power of a lamp, so the numbers on the packaging must be divided by the number of groups of LEDs - 16000/4 (2 groups for “near”, 2 groups for “far”) - the actual values will be only 4000 Lumens.

The cost of such lamps is reasonable, you can order them on Aliexpress >>>

NIGHTEYE H4

Another interesting specimen from a Chinese manufacturer. The lamp is assembled with very high quality; the developers used Korean Seoul Y19 LEDs, which are in no way inferior to Philips products.

The previous lamp model under the Nighteye brand was in quite high demand, largely due to the precise placement of the LEDs, ensuring the correct boundaries of the luminous flux, as well as long-term operation without breakdowns. In the new generation, the developers have retained all the advantages of the lamp, which is why customers love it.

The manufacturer indicates the lamp power as “total”, so the indicated numbers must be divided by the number of groups of LEDs - 8000/4 (2 groups for “near”, 2 groups for “far”) - the actual values will be only 2000 Lumens. It is quite enough for good illumination with headlights under the H4 socket.

The cost of the lamp is also very reasonable, you can order it on Aliexpress >>>

4DRIVE H4

Another model of H4 LED lamps, which is in great demand due to its low cost and high power, is the 4drive H4 model.

A fairly well-assembled lamp, assembled on the basis of Philips LEDs. Its design uses large LEDs that provide a dense luminous flux of daytime white color. The power of the luminous flux is indicated for each lamp, that is, the “low” and “high” beams account for 3800 Lumens each. Great attention has been paid to the placement of the LEDs, so that the headlights will not dazzle oncoming cars.

The model features a large aluminum radiator and a cooler - a fan that provides good cooling of the control electronics.

The cost of the lamps is one of the lowest, and there are no difficulties with ordering them, since the lamps are sold in Russia. Lamps can be ordered at a discount (the base is indicated by phone)

Can H4 LED bulbs be installed in headlights?

It should be noted that the installation of LED lamps in headlights designed for halogen lamps is expressly prohibited. This follows from the “List of faults for which operation of the vehicle is prohibited.” Clause 3.1 states:

The number, type, color, location and operating mode of external lighting devices do not meet the requirements of the vehicle design.

As a punishment for the installation of lighting devices that do not comply with the “Regulations”, deprivation of rights is provided (Part 3 of Article 12.5 of the Code of Administrative Offenses):

Driving a vehicle... ...does not comply with the requirements of the Basic Regulations for the admission of vehicles to operation and the duties of officials to ensure road safety..

Involves deprivation of the right to drive vehicles for a period of six months to one year with confiscation of the specified devices and accessories.

Whether the advantages of installing LED lamps in “halogen” headlights outweigh the disadvantages that may arise due to possible problems with the traffic police is something for everyone to decide for themselves.
